Has anyone read the book Lost Connections

The writer who is not a medical professional purports that anxiety and depression has overwhelmingly social and environmental causes related to modern life/late capitalism/past traumas/negative life circumstances instead of the brain chemical model.

And he is of the opinion that antidepressants are no better than placebo and cannot and have never worked for people. He thinks depressed and anxious people need to change their lives, or more broadly, that society must change, for these illnesses to improve on a mass scale. I agree, however. He does not discuss the many other numerous classes of drugs that genuinely help people. It's rather glib to imply masses of people don't have endogenous brain issues because it implies they need not seek medical care/treatment. There can be an endogenous brain issue as the intermediary mechanism between a cause (say, genetics or life factors) and the presenting symptoms.
